This week, chaos consumed The Block as not one, but two teams failed to finish the en-suites of their guest bedrooms.

Contestants were tasked with creating self-contained guest suites complete with connecting bathrooms and point-worthy additions, such as kitchenettes, lounges and walk-in wardrobes.

The Blockheads were also expected to prepare for The DomainListings and Buyers Jury challenge, where they hosted 100 potential buyers who voted on their favourite homes.

The stacked week saw three teams fail to finish and one come out on top.

Emma and Ben emerged victorious on Sunday night’s episode, nabbing the title of best guest suite with 29.5 points and scoring two tens on the board.

The space boasted a concealed walk-in wardrobe, a kitchenette complete with sage green tiles and copper tap-ware, and a balcony.

The bathroom, which judge Darren Palmer dubbed a ‘little gem’, stunned the judges with blue tiles and a spacious layout.

‘This is a very high bar,’ he added.

What’s more, the pair also won the $50,000 from Domain’s Open House challenge and a secret bonus-point gnome, catapulting them to the front of the race.

However, other teams struggled to finish the sprint, let alone make the podium.

Both Britt and Tazz and Mat and Robby had bathrooms that were still under construction during the judges’ inspection.

Han and Can failed to finish their makeup station, while their space lacked styling and a kitchenette, which was included in the other houses’ designs.

It comes after a secret wine cellar sparked one of the biggest blow-ups of the season.

What started as a glossy open-for-inspection day with 100 potential buyers quickly turned into a war of words, with alliances breaking down and friendships pushed to the brink.

Emma and Ben’s bathroom (pictured), which judge Darren Palmer dubbed a ‘little gem’, stunned the judges with blue tiles and a spacious layout.

Mat, usually the easy-going tradie of House Three, lost his cool after discovering that ‘Block sweethearts’ Ben and Emma had unveiled plans for their very own underground wine cellar – a move he branded a blatant rip-off of his and Robby’s prized feature.

‘Fing get your own ideas!’ Mat fumed after Robby broke the news, accusing the pair of ‘copying’ their design.

‘You can’t win a thing so you try and copy our ideas. F**k off… dumba**es.’

The tirade shocked viewers and left the visiting crowd stunned, with Robby convinced that Ben’s earlier body corporate meeting was a ruse to suss out cellar costs.

But in a stunning twist, Ben and Emma had the last laugh – their property was voted the favourite by the visiting buyers, scoring 24 per cent of the vote and snatching the $50,000 prize.

That left Mat and Robby in second place on 23 per cent, with Britt and Taz third (21 per cent), Sonny and Alicia fourth (19 per cent) and Han and Can last (13 per cent).

Despite their fury, Mat and Robby managed to clap for their rivals – though the simmering tension was written all over their faces.
